Create a tiddler called TodaysHoliday which says It's ''The Day'' today!, where The Day is the name of the holiday that is occurring today, according to the data tiddler. Unless you happen to be doing this exercise on one of the four holidays listed above, you'll need to make up and add your own holiday with today's date so you can check the result.

You may need to look at the documentation for the now procedure to figure out how to get today's date in the month/day format.
